A pyramid with a triangle as base is considered as a tetrahedron. It is a three dimensional polyhedron with 4 equilateral triangles as its sides. If one would look at the word tetrahedron, it literally means "with four planes".

Tetrahedron
A three-dimensional figure or shape, such as a tetrahedron, has four faces. These faces are equilateral triangles. A tetrahedron also has four vertices and 6 edges.

A triangular based based pyramid is a TETRAHEDRON. It becomes a regular tetrahedron if the four triangles, that make up its shape, are REGULAR, that is they are all the same size by area and shape; that is they are congruent. The word 'polyhedron' means a solid shape of any number of sides.
tetrahedron is a 4 faced 3d shape.
It is a 3-D shape because a tetrahedron can be folded into a net!
Well, a tetrahedron has four sides. A regular tetrahedron is a triangular pyramid.
Triangle In a tetrahedron, all sides are triangles
It have four bonds and no lone pairs.So shape is tetrahedron.
A tetrahedron is a 3-dimensional shape - a triangular pyramid. It is NOT a number.

It can be but need not be.
